PTHREAD_ATTR_SETSTACKADDR(3Linux Programmer's ManuPTHREAD_ATTR_SETSTACKADDR(3)



NAME
       pthread_attr_setstackaddr,  pthread_attr_getstackaddr  -	 set/get stack
       address attribute in thread attributes object

SYNOPSIS
       #include <pthread.h>

       int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
       int pthread_attr_getstackaddr(const pthread_attr_t *attr, void **stackaddr);

       Compile and link with -pthread.

DESCRIPTION
       These functions are obsolete: do not use them.	Use  pthread_attr_set-
       stack(3) and pthread_attr_getstack(3) instead.

       The   pthread_attr_setstackaddr()   function  sets  the	stack  address
       attribute of the thread attributes object referred to by	 attr  to  the
       value specified in stackaddr.  This attribute specifies the location of
       the stack that should be used by a thread that  is  created  using  the
       thread attributes object attr.

       stackaddr  should point to a buffer of at least PTHREAD_STACK_MIN bytes
       that was allocated by the caller.  The pages of	the  allocated	buffer
       should be both readable and writable.

       The  pthread_attr_getstackaddr()	 function  returns  the	 stack address
       attribute of the thread attributes object referred to by	 attr  in  the
       buffer pointed to by stackaddr.

RETURN VALUE
       On  success,  these functions return 0; on error, they return a nonzero
       error number.

ERRORS
       No errors are defined (but applications should  nevertheless  handle  a
       possible error return).

VERSIONS
       These functions are provided by glibc since version 2.1.

ATTRIBUTES
       For   an	  explanation	of   the  terms	 used  in  this	 section,  see
       attributes(7).

CONFORMING TO
       POSIX.1-2001  specifies	these  functions  but  marks them as obsolete.
       POSIX.1-2008 removes the specification of these functions.

NOTES
       Do not use these functions!  They cannot be portably used,  since  they
       provide	no  way	 of specifying the direction of growth or the range of
       the stack.  For example, on architectures with a stack that grows down-
       ward,  stackaddr specifies the next address past the highest address of
       the allocated stack area.  However, on architectures with a stack  that
       grows  upward,  stackaddr specifies the lowest address in the allocated
       stack area.  By	contrast,  the	stackaddr  used	 by  pthread_attr_set-
       stack(3)	 and pthread_attr_getstack(3), is always a pointer to the low-
       est address in the allocated stack area	(and  the  stacksize  argument
       specifies the range of the stack).
